hi,
">>>As the Array fills up it will become considerably slower. And there are latencies that might bring down the real world performance even more down. ..."
this had been the main advantage of the good old stone filesystem ("which was considered way too expensive ...") - i did have occasions, where i got the message "0 frames free", when rendering, and still playback & performance was as expected!
also deleting & loading new footage wouldnt cause noticable performance drop, even over 1 year or more!
i think Quantels filesystem had similar behaviour - currently you can get BrightTech on Rorke Aurora RAIDs, which deliver a rather consistent performance - of course, they arent cheap ... -
but you can also use an internal 3disk stripe - depending on your expectations ...
